A system for securely storing application keys is comprised of a database system, a peripheral hardware security module and cryptographic keys, wherein cryptographic keys comprise application keys, intermediate keys and a master key. Application keys are grouped according to characteristic and are associated with a particular intermediate key, which is utilized to scramble and descramble application keys within the associated group. Intermediate keys are associated with the master key, which is utilized to scramble and descramble the intermediate keys. Scrambling and descrambling of keys is performed within the peripheral hardware security module.

Cryptographic key backup and escrow system

A system is comprised of a user and a group, wherein the group is comprised of a group leader and a group of M members where M is equal to or greater than one. The group leader generates a group public key and a group leader 'master' private key. The group leader creates a personalized watermarked or decryption key, also referred to as an individual private key, for each group member. The individual private key uniquely identifies each group member. The group leader distributes the individual private keys to each of the group members. Each group member receives from a user a message encrypted using the group public key. Each of the group members uses its individual private key to decrypt the encrypted message sent by the user to the group.

Public key encryption for groups

Systems and methods for an information system security infrastructure are described. One embodiment of the present invention comprises global Internet-scale defense infrastructure, referred to as the Intrusion Detection Force (IDF). The IDF comprises a virtual infrastructure implemented on top of an existing network, such as the Internet. The IDF enables secure information sharing and intelligent data analysis and response. The node (e.g.of FIG.) is the most primitive entity in the IDF architecture, and may be a switch, router, server, or workstation. The IDF may be implemented in small networks of computers or may be utilized by millions of hosts throughout the Internet, spanning different organizations, countries, and continents.

Systems and methods for enhanced network security

A system such as in a networked computer system comprising a user, an application server, a gatekeeper server and an authentication server. Communication within the system is managed by the gatekeeper server, wherein the user communicates with the authentication server and the application server through the gatekeeper server. Once the user has been initially authenticated by the authentication server, the user may request application services from a plurality of application servers within the networked computer system without having to be re-authenticated.

Authentication system for networked computer applications

A random number generator includes one or more pseudorandom data sources that generate pseudorandom data, a randomness accumulation facility that receives pseudorandom data from the one or more pseudorandom data sources, a storage facility that stores a random value generated by the randomness accumulation facility, and an application programming interface ('API'), operating independently from the operation of the randomness accumulation facility, that retrieves, upon request by a software application, the random value currently stored in the storage facility and provides a random number to the software application. The pseudorandom data is hashed with a previously-stored random value and a first counter value and may be encrypted before storing in the storage facility. Likewise, the API hashes the current random value with a second counter value before outputting the random number thus generated, decrypting the current value first if necessary.
